REGULATOR FOB. VAPOR HEATING SYSTEMS.

Application filed September 11 1919. Serial No. 323,104.

To all whom it may concern Be it known that I, HARRY A. CoNNnRs, a citizen of the United States of America, and a resident 'of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Regulators for Vapor Heatin Systems, ofwhich the following is a specification.

My invention relates to a float actuated means for regulating the damper and the draft of furnaces of vapor systems.

One of the disadvantages of these float actuated regulators now in use is that under certain abnormal conditions the water in the system will boil over or escape through the housing of the float. j

An object of my invention is an automatic means for preventing water escaping at the float.

Another object of my invention is a positive means for actuating the draft and the damper from the float. I I *These and other objects are attained by the means described in the specification and illustrated in the accompanying drawings in which Fi 1 is a perspective view of a furnace showing the method of installing the regulator embodying my invention.

Fig. 2, is a cross sectional view of my regulator taken upon the line 2-2 of Fig. 8.

Fig. 3, is a plan view of a portion of the cover on my regulator, showing the cross arm and means for adjusting it.

Fig. 4, is a fragmental view of the upper portion of the housing showing a sectional view of a cup valve.

Fig. 5, is a erspective view of the metal mounting on tie gauge.

Fig. 6, is'a detail of an attachment for adjusting the cross arm.

Fig. 7, is a fragmental perspective view of a detail of the cross-arm and a sleeve supporting same.

My invention relates to a heat regulator for use on furnaces, comprising a housing A, inclosing a float C which is actuated by the water in the furnace boiler P, contained within the furnace housing P the float in turn actuating a lever K and a cross-arm by means of which the draft or fuel supply on the furnace is regulated, thereby maintaining a certain pressure. Refer ring to the drawings.

My regulator comprises a housing A with its cover a, which are made air andwater tight by the fibrous lining a between them.

Mounted in the cover is the valve casing B whose upper portion .7) 'isfthreaded exter nally and has three fapertures g, g g extending vertically thru the top into the hol-j low' central cylindrical portion 6 of the valve casing. The holes g, 9 are relatively smaller than g g, g are air" outlets and are th means of liberating the air from the interior of housin'gA which is forced into the housing by way of the pipe f when steam is admitted to the radiator. The air which accumulates in the radiator of the heating system is forced out of the radiator and thru the pipe f by the steam. The escape of the steam from the radiator is precluded'by various valves mounted on theradiator and which practice is common n the art." The lower portion 6 of valve casing B is shaped in the form of a semi-spherical bodyhaving I aground beveled edge 6 located interiorly of it and forming aseat for valve D.

Valve stem 03 slides loosely in the aperture g in the valve casing and has fastened to its lower end a valve D whose beveled edge d seats on the edge '6 making an air and water tight joint when seated. V

A small rod 0 fastened to thebase of valve D connects the valve with float C, the small rod being fastened in the upper portion of float C. Any movement of the float verti cally, would move the valve,, 'this' in turn giving movement tothe valve stemcZ. which is the means of actuating the cross-arm and lever as will be explained hereafter. The housing is connected to the boiler of the furnace by pipe F which is inserted at the base of the housing. Anair return pipe "having the check valve f, is inserted in the upper part of the housing. This check valve is inserted for reasons that will hereinafter be described.

The sleeve Gr isflocated above the cover and valve casing and is slidably mounted upon the cross arm' H, and the valve stem d extends slidably through thesleeve. The whole upper portion of the valve stem d is threaded andtwo lock-nuts d are. placed upon it. By having the lock-nuts at the up per extremities of valve stem da-the position of thefloat is regulated in accordance with the pressure desired in the system. I The cross arm is pivotallyinounted ona vertically adjustable bracket h I and. slides lo s y ru. l t 9 i G and isQ ntr He by the bolt h. In order that thecross-arm H may have a reciprocating motion in relation to the sleeve G, due to the fact that it is hinged on k and has a vertical movement imparted to it by sleeve G, it is provided with an elongated slot 71 extending longitudlnally of itself. The pivotal mounting of the cross arm is accomplished by having the end of the cross-arm H on which is fastened the chain n, weighted, which tends to move the Qr ss-armupWard at G, its upward movement being limited by the two lock-nuts d andrthe weight of float C.

The chain n is fastened at its lower end to ve K, wh h runs arall W h he urnacel and is supported midway by the support Z which, isfmou e i the p. of h furnace, Chain m is fastened at its upper end to lever K, being a continuation of chain 02. Its lower extremity is fastened to the hinged draft door Y which is of sufiicient weightto retain the sleeve in normal engagement with the lock nuts. Fastened to theother end of lever K is the chain m, connecting the flue check draft and lever K,

Mounted on housing A is a gauge consistof the metal mounting 15', two rods 6 which pass thru the perforations e in the mounti g a d a e held i pl ce by he collar e Thelrods serve to keep the mounting stationary. A glass tube 6 is connected up in the usual way with the casing A, Mounting E is graduated, as shown in Fig. 5, the line 6 indicating the water line at. normal. This gauge, indicates-the pressure that is being ii d' edi i PlateH in Fig. 6, is a means for adjusting the cross-arm'H to any desired position, for installation of the regulator.

hacherns n, m nd are onne te a heretofore explained, of use on furnaces where, coal is used a fuel. On a gas f-urnace the lever K together with the chain mr would be eliminated, and the chain n would" be continued down to the gas supply turning, it off or on in the usual manner In operation, when the pressure in the systemfisincreased the water in the casing rises,;pushing up on the float which in turn permits the arm H to be moved upon the pivot it because of the weight of the door Y \i'herefore the lever K is actuated and the door ,Y closes, and the check draft is opened, thereby decreasing the flame and causing the pressure to decrease when the float would drop again causing the draft to be opened a ain,

The float C is made of a weight suflicient to, counterbalance the weight of the door Y and the chains operatingbetween the crossarm, the lever K and the check draft and the draft doors, It will therefor be apparent that normally when there, is no pressure within the heating system, the weight of the float C will be suflicient to, retain the cross: arm and the lever K in such position that normally the draft dOOr Y is opened and that the check draft is closed. The raising of the float C serves merely to permit the weight of the draft door Y to close the draft door and open the check draft.

Should the movement of the draft door Y be impeded by any abnormal condition such as cinders becoming lodged thereunder, or the chains becoming twisted or broken, and the continued heat of the fire, should raise the water in the system above its normal degree, this would carry the float forward and close the valve 1) against the seat 6 This wouldprevent the water of the system from escaping through the holes in the top of the sln Y The check valve f prevents any air being drawn into the system when-the pressure thereof falls, and when. the pressure rises permits air from: the heating system to escape out thru holes g and Having thus described my invention, what I claimis I l.
